Data Sources¶
In this section, the data sources which are stored in soapy are listed and a description of how they are obtained is given.
Simulation Run Data¶
The following sources of data are recorded for each simulation run and are saved as a fits file in a time stamped run specific directory inside the simName
directory. They can be accessed by sim.<data>
, where <data>
is listed in the “Internal data structure” column. As the storing of some of these data sources can increase memory usage significantly, they are not all saved by default, and the flag must be set in the configuration file.
Data | Saved filename | Internal data structure | Description |
---|---|---|---|
Instantaneous Strehl ratio | instStrehl.fits |
instStrehl |
The instantaneous strehl ratio for each science target frame |
Long exposure Strehl ratio | longStrehl.fits |
longStrehl |
The long exposure strehl ratio for each science target frame |
Wavefront Error | WFE.fits |
WFE |
The corrected wave- front error for each science target in nm |
Science PSF | sciPsf_n.fits |
sciImgs[n] |
The science camera PSFs
where n indicates the
camera number |
Residual Science phase | sciResidual_n
.fits |
sciPhase[n] |
The residual uncorrected
phase across science
target n |
WFS measurements | slopes.fits |
allSlopes |
All WFS measurements stored in a numpy array of size (nIters, totalSlopes) |
WFS Frames | wfsFPFrames/
wfs-n_frame-i
.fits |
sim.wfss[n].
wfsDetectorPlane |
WFS detector image, only
last frame stored
in memory. Can save each
frame, i , from wfs
n |
DM Commands | dmCommands.fits |
allDmCommands |
DM commands for all DMs present in numpy of size (nIters, totaldmCommands) |
